[pulseaudio-discuss] How can I record from multiple inputs

[Dark Shadow]

I'm trying to record some game footage and include some talking but I
can't get audio to record from multiple sources.


I have the game audio coming into the system via a loop back cable
into line-in which works
I also have a Bluetooth headset which can work for my voice on its own

But I can't record from both simultaneously since Pulseaudio only lets
me select one

My ideal setup would be
audio output via BT headset
I can hear the line-in input also via module-loopback which I already do
but I see problems if the voice is multiplexed with since I don't want
voice looped back to the output
the OBS recording software records both line-in and voice (BT) either
via some virtual multiplexed virtual input or being presented with
multiple input options from Pulseaudio (prefered over virtual)

I tried going through the list of modules on the wiki but couldn't
figure out how to do anything.
